#### What are ComparisonFormulas?

Comparison Formulas are, as the title suggests, a way to make a comparison between two variables. This is incredibly useful when creating your bot and improving your chatbot flow.

With these formulas you will be able to redirect a user down to the relevant flow of your bot if their answers score beyond a desired threshold for lead generation and qualification, to calculate whether a sum is over a predefined budget, and many more use cases.

Keep on reading to find out all the possibilities with the Comparison Formulas and how to use them.
